Yes it's probably tedious, but when you're really into something, at that age, you just persevere because you can :) Also young children are incredible on touchscreens, small fingers and they grew up with them :) [I'm the opposite, I have some stress/burnout related tremors in my fingers, some mornings (when it's worst) I can hardly control the device's apps, let alone typing]
